T 0 (all whom it may concern.

Be it known that I, BAssnrT'JoNEs, a citizen of the United States andresiding at Mahwah, Bergen county, tate of New Jersey, have inventedcertain new and useful- Improvements 1n lnghtl-ng-Fixtures, of-

cipal features of the invention reside in the means for suspending thereflectors so that the lower may be removed easily without disturbingthe upper reflector or the two parts may be removed together as a unit.@ther objects and features of novelty will be apparent from thedescription taken in connection with the drawings, in which- Figure l isan elevation of a fixture constructed in accordance with the presentin-.

vention, half being shown in section;

Fig. 2 is a sectional plan view taken substantially on the line 22 ofFig. 1; and

Fig. 3 is a perspective view of one of the clips supporting the lowerreflector or plate. Referring to the drawings the reference numeral 10indicates the upper metal reflector of a two part lighting fixture. Thisreflector may be of any suitable shape and is open at its upper andlower ends. According to the present inyention, this reflector issuspended on three arms 11, these arms at their upper ends being securedto the cone or support 12 associated with the lamp socket 13. The lowerends of the arms 11 are formed with the hooked portions 14 adapted toreceive the lower edge of the reflector 10. The arms 11 may be made fromany suitable material. If constructed from metal strips or bars, theymay be twisted as indicated at 15 and 16, so that'the greater portion oftheir lengths are disposed edgewise. Preferably the hooked shaped ends 11 are slightly oflset outwardly, so that the reflector may be moreeasily removed, as will be explained hereinafter. 1

At the lower end of the reflector 10 is disposed a reflector ordiffusing plate 17, although this member may have other shapes than thatshown. F or the purpose of suspending this member 17, a plurality ofclips 18 are secured to the reflector l0 and shaped to engage andsupport the plate or disk 17. In the form shown there are three of theclips 18, two of which are secured to the reflector 10 in any suitablemanner, as by means of the'rivets 19. One of the clips, indicated by thereference numeral 20, is preferably formed with an elongated aperture 21for a bolt 22, so that when the'bolt 22 is loosened, the clip may bedisplaced sufficiently so that the plate 17 may be removed.

While the members 10 and 17 may be of various shapes in so far as thesuspending means is concerned,'T prefer to use a flat member 17 inconjunction with an upper reflector 10 which has its smaller opening atthe bottom and which flares rapidly outwardly and upwardly so that it ismarkedly concave on its outer or non-reflecting surface, the. convexsurface catching and reflecting the rays from the li' ht, source. Member10 preferably flares su ciently so that its lower edgeis nearly verticalwhile its upperJand-.- outeredge is nearly hori- Patented Nov. a, mac.

zontal. Thisform gives a desirable light. distribution. and goodefliciency in a fixture of cheapand simple'construction.

From the foregoing description it is apparent, to remove bothreflectors,it is merely necessary to raise'the upper reflector, with the lowerreflector plate attached thereto, so that the hooks on-the ends of thearms 11 become disengaged fromthe lower edge of the upper reflector.Then the upper reflector is moved slightly laterally so as to permit twoof the hooks to pass through the lower open end of the upper reflector.The arms 11 are more or less yielding and the offset ends, if

provided, aid in permitting this lateral movement. 1

To remove the lower reflector or separate the two reflectors, the boltor screw 22' is loosened sufiiciently so that the clip 20 may bedisengaged from the edge of the lower reflector, whereupon saidreflector may be disengaged from the other two clips.

It is apparent from the foregoing, that according to the presentinvention the lower reflector may be removed without disturbing theupper reflector or the means for supporting the same, or both reflectorsmay be removed simultaneously.

Although a specific form of the invention has been described in detail,it is to be understood that the invention is not limited, but

includes modifications and changes which come Within the scope of theappended claims.

Having thus described the invention what is claimed as new and desiredto be secured by Letters Patent is:

1. A lighting fixture including in combination, a support, an annularreflector having open ends, a plurality of spring arms secured to thesupport and having hooked ends receiving the lower edge of saidreflector, said hooked ends of the spring arms being offset from saidsupport and said arms passing through said annular reflector, a circularreflecting member below said reflector and clips secured to saidreflector and supporting said member, one of said clips. beingremovable.

2. A lighting fixture including in combination, a support, an annularreflector having open ends, a plurality of arms secured to the supportand to said reflector, a circular reflecting member below saidreflector, and clips secured to said reflector and supporting saidmember, one of said clips being removable.

3. A lighting-fixture including in combination, a support, an annularreflector ha"- ing open ends,a plurality of arms secured to the supportand to said reflector, a circular reflecting member below saidreflector, and clips secured to said reflector and supporting saidmember, one of said clips having an elongated slot therein and a bolt insaid slot whereby the clip may be readily disengaged from said member.

In testimony whereof I affix my signature.
